Description

Technical Field

[0001] This utility model relates to the field of gas ring network switchgear technology, specifically a door structure for a gas ring network switchgear. Background Technology

[0002] Gas-fired ring network switchgear is a key piece of equipment in modern power distribution systems and is widely used in power distribution and protection in urban power grids, industrial parks, and important load centers.

[0003] According to CN211829718U, a gas ring network switchgear door hanging device is disclosed. This technology discloses a technical solution including "a cabinet frame, a right side panel, a left side panel, a lower cabinet door panel, a left hanging plate, a right hanging plate, and hooks. The left side panel and the right side panel are arranged on the left and right sides of the cabinet frame. The lower cabinet door panel is installed on the front side of the right side panel and the left side panel. The left hanging plate and the right hanging plate are connected to the lower cabinet door panel. The hooks are arranged on the left hanging plate and the right hanging plate." It has the technical effects of "adopting a door hanging installation method, which improves the speed at which maintenance personnel can open the lower cabinet door panel during maintenance under safe operation, while avoiding the need to find special tools for maintenance, thereby improving maintenance efficiency, reducing power outage time, and increasing output value. On the other hand, the lower cabinet door panel device realizes the door hanging method with a few simple parts, which reduces the number of parts, makes installation convenient, and thus reduces processing costs and improves installation efficiency and reliability."

[0004] The above-mentioned gas ring network switchgear door structure has insufficient operational safety during disassembly. Specifically, after the door panel is unlocked, there is a lack of effective support points, making it difficult for operators to simultaneously control the stable displacement of the door panel. This can cause the door panel to suddenly fall or shake due to gravity, which may easily lead to equipment collisions or personnel safety risks. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a door structure for a gas ring network switchgear. The door structure uses simultaneous two-hand operation to achieve smooth unlocking and support, and utilizes the mechanical self-locking principle to complete rapid installation and locking, thereby improving maintenance efficiency and safety reliability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas ring network switchgear door structure, comprising a switchgear body, wherein a door-hanging mechanism is provided on the switchgear body for protecting the interior of the switchgear body, the door-hanging mechanism comprising:

[0007] The load-bearing components include a frame fixed to the side of the switch cabinet body;

[0008] The main components include a door panel set inside the frame. Guide plates are set on both the upper and lower sides inside the door panel, and the two guide plates are symmetrically arranged. Guide oblique holes are opened on both the left and right sides inside the guide plates, and the two guide oblique holes are symmetrically arranged. Pins are slidably installed on both the left and right ends of the guide plates through the guide oblique holes. Mounting heads are fixed to the outer ends of the pins. A crossbar is fixed in the middle inside the guide plate. Balance bars are fixed on both the left and right sides of the guide plate facing the crossbar, and the balance bars are slidably installed through the crossbar. Springs are sleeved on the balance bars, and the springs are located between the crossbar and the balance bars.

[0009] Preferably, the main component further includes bent rods fixed to the left and right ends of the guide plate, and a handle is fixed between the outer ends of the two bent rods.

[0010] Preferably, the main component further includes a limiting bracket sleeved on the pin, and the limiting bracket is fixed to the inner wall of the door panel.

[0011] Preferably, the main component further includes a slot formed in the door panel, and the bent rod passes through the slot.

[0012] Preferably, the load-bearing component further includes a side door hinged to the side end of the frame, and mounting holes are provided on the inner walls of both ends of the frame to cooperate with the mounting head.

[0013] Preferably, a wear-resistant bushing is embedded in the guide oblique hole, and the pin is in sliding fit with the wear-resistant bushing.

[0014] Beneficial effects

[0015] This utility model provides a door structure for a gas ring network switchgear. Compared with the prior art, it has the following advantages:

[0016] 1. By pulling the handle in conjunction with the bent rod, the guide plate moves vertically. During this movement, the symmetrical guide holes inside the guide plate force the pin to move horizontally inward. The pin then pulls the mounting head out of the mounting hole, releasing the lock and allowing the main component to be removed. When installing the main component, first pull the handle to retract the mounting head inward, then place the main component into the frame. Release the handle; the spring's return pressure pushes the guide plate in the opposite vertical direction. The guide plate, through the guide holes, drives the mounting head on the pin to insert horizontally outward into the mounting hole, completing the locking process. This achieves quick door panel removal and self-locking, is simple and reliable to operate, and improves maintenance efficiency.

[0017] 2. By setting two symmetrically distributed handles, operators can hold and pull both handles simultaneously with both hands when disassembling or assembling the main components. The balanced movement of the upper and lower guide plates is achieved by applying force simultaneously from both sides, allowing all mounting heads to exit from the mounting holes at the same time to complete the unlocking. More importantly, it provides operators with two natural gripping points. During operation, the hands can naturally bear the overall weight of the main components, achieving effective support and stable control of the door panel. This avoids the safety risks caused by the door panel suddenly falling or shaking due to gravity after unlocking, significantly improving the controllability and safety of the disassembly and assembly process, and realizing the integrated completion of unlocking operation and grip support.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a gas ring network switchgear door structure, including a switchgear body 1, a door-hanging mechanism 2 provided on the switchgear body 1 for protecting the interior of the switchgear body 1, the door-hanging mechanism 2 including:

[0025] The supporting component 21 includes a frame 211 fixed to the side of the switch cabinet body 1;

[0026] The main component 22 includes a door panel 2212 disposed inside the frame 211. Guide plates 221 are provided on both the upper and lower sides of the door panel 2212, and the two guide plates 221 are arranged symmetrically in the upper and lower parts. Guide oblique holes 222 are provided on both the left and right sides of the guide plate 221, and the two guide oblique holes 222 are arranged symmetrically in the left and right parts. Pins 223 are slidably installed on both the left and right ends of the guide plate 221 through the guide oblique holes 222. Mounting heads 224 are fixed to the outer ends of the pins 223. A crossbeam 225 is fixed in the middle of the guide plate 221. Balance bars 226 are fixed on both the left and right sides of the guide plate 221 facing the crossbeam 225, and the balance bars 226 are slidably installed through the crossbeam 225. A spring 227 is sleeved on the balance bar 226, and the spring 227 is located between the crossbeam 225 and the balance bar 226.

[0027] In this embodiment, pulling the handle 229 in conjunction with the bent rod 228 moves the guide plate 221 vertically. When the guide plate 221 moves, the symmetrical guide holes 222 inside force the pin 223 to move horizontally inward. The pin 223 then drives the mounting head 224 out of the mounting hole 213, releasing the lock and allowing the main assembly 22 to be removed. When installing the main assembly 22, first pull the handle 229 to retract the mounting head 224 inward, then place the main assembly 22 into the frame 211. Then release the handle 229; the return pressure of the spring 227 pushes the guide plate 221 to move in the opposite direction vertically. The guide plate 221, through the guide holes 222, drives the mounting head 224 on the pin 223 to horizontally insert outward into the mounting hole 213, completing the locking. This achieves quick disassembly and self-locking of the door panel, is simple and reliable to operate, and improves maintenance efficiency.

[0028] Specifically, the main component 22 also includes bent rods 228 fixed at the left and right ends of the guide plate 221, and a handle 229 is fixed between the outer ends of the two bent rods 228.

[0029] In this embodiment, by setting two handles 229 symmetrically distributed vertically, the operator can use both hands to hold and pull the two handles 229 simultaneously when disassembling and assembling the main component 22. The balanced movement of the upper and lower guide plates 221 is achieved by applying force synchronously on both sides, so that all mounting heads 224 can be simultaneously withdrawn from the mounting holes 213 to complete the unlocking. More importantly, it provides the operator with two natural gripping points. During the operation, the hands can naturally bear the overall weight of the main component 22, achieving effective support and stable control of the door panel. This avoids the safety risks caused by the door panel suddenly falling or shaking due to gravity after unlocking, significantly improving the controllability and safety of the disassembly and assembly process, and realizing the integrated completion of unlocking operation and grip support.

[0030] Specifically, the main component 22 also includes a limiting bracket 2210 sleeved on the pin 223, and the limiting bracket 2210 is fixed to the inner wall of the door panel 2212.

[0031] In this embodiment, the pin 223 is always radially constrained by the limit frame 2210 during horizontal movement, thereby ensuring that the mounting head 224 can be accurately aligned and smoothly inserted into or removed from the mounting hole 213 on the frame 211.

[0032] Specifically, the main component 22 also includes a slot 2211 formed on the door panel 2212, and the bent rod 228 passes through the slot 2211.

[0033] In this embodiment, the handle 229 extends to the outside of the door panel 2212 through the slot 2211, providing the operator with a clear and intuitive operation, while the rest of the structure is hidden inside the door panel 2212, maintaining the integrity of the appearance.

[0034] Specifically, the load-bearing component 21 also includes a side door 212 hinged to the side end of the frame 211, and mounting holes 213 are provided on the inner walls of both ends of the frame 211 and cooperate with the mounting head 224.

[0035] In this embodiment, a side door 212 is hinged to the side of the frame 211, forming a layered protection with the main body component 22. When it is necessary to inspect and maintain the auxiliary equipment such as secondary components and wiring terminals inside the switch cabinet body 1, the side door 212 must be opened first, and then the main body component 22 can be removed from the frame 211 through the operating handle 229 to fully expose the internal structure of the equipment. This ensures the safety of the equipment during operation and prevents accidental direct contact with live parts.

[0036] Specifically, a wear-resistant bushing is embedded in the guide oblique hole 222, and the pin 223 slides with the wear-resistant bushing.

[0037] In this embodiment, when the guide plate 221 moves in the vertical direction, the pin 223 slides smoothly in the inclined hole through the guidance of the wear-resistant bushing, reducing frictional resistance and wear during the movement.

[0038] The working principle and usage process of this utility model are as follows: First, when it is necessary to maintain the inside of the switch cabinet body 1, the operator first opens the side door 212 hinged to the side of the frame 211 to expose the internal operating space. Subsequently, the operator holds the two symmetrically distributed handles 229 with both hands and pulls them inward simultaneously. This causes the upper and lower guide plates 221 to move synchronously in the vertical direction via the bent rod 228. When the guide plates 221 move, the symmetrical guide holes 222 inside force the pin 223 to move horizontally inward under the constraint of the limit frame 2210, causing the mounting head 224 to exit from the mounting holes 213 at both ends of the frame 211 and release the lock. At this time, the operator continues to hold the handles 229 and can smoothly remove the entire main component 22 from the frame 211, effectively preventing the door panel from suddenly falling due to gravity. During installation, the operator first pulls the handles 229 to keep the mounting head 224 in a retracted state, aligns the main component 22 and places it into the frame 211, and then releases the handles 229. At this time, the rebound pressure of the spring 227 pushes the guide plate 221 to move in the opposite direction. Through the guiding action of the guide holes 222, the pin 223 moves horizontally outward, allowing the mounting head 224 to accurately insert into the mounting hole 213 and complete the automatic locking.
